SIDE BEARING Fon RAILWAY-CARS.

SPECIFICATION forming part Of Letter Patent N0. 686,118, dated November5, 1901.

Application filed Mareh'ZS, 1901. Serial No. 52,575. (No model.)

T @ZZ wiz/0m it may concern.-

Be it known that we, SANDFORD NoR'rHRoP and ANDREW G. STEINBRENNER,citizens of the United States, and residents of the city of St. Louis,in the State of Missouri, have invented certain new and usefulImprovements in Side Bearings for Railway-Cars, of whichroller-carriage.

the followingis a full, clear, and exact description, reference beinghad tothe accompanying drawings, forming part ot' this specification.

Our invention relates to that class of bearings used to support thebody-holsters of railway-cars in such manner as to reduce the frictionalbearing between said bolsters and the parts by which they are supportedand on which they ride.

The invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a perspective View of our bearing looking at the outer facethereof. Fig. II is a longitudinal sectional View taken on the line IIIl, Fig. I. Fig. III is a cross-sectional view taken on the line IIIIII, Fig. II. Fig. IV is a detail view illustrating the engagement ofthe outer rock-shaft rocker-arm with the bolster-receiving plate.` Fig.Vis a detail perspective view of ther connection between the innerrock-shaft rocker-arm and the 1 designates the body of the bearing,preferably of box form, which is designed to be applied to thetruck-bolster by suitable means, such as bolts passed through ears 2,that project from the inner'face o f the body 1.

3 designates a hardened I bearing plate mounted on top of the body 1,one end of said plate being seated beneath an overhanging shoulder 4,integral with the body 1, the opposite end of the plate being retainedin position by a cross-strip` 5, that is riveted or otherwise suitablyaftixed to the body 1. The bearing-plate 3 is of sufficient width toproject beyond the side faces of the body l, so that the edges of theplate will overhang beyond the sides of said body to receive theengagement of retaining-ears 6 pendent from the roller-receivingcarriage 7 in order that said carriage may be held from displacement inits movement above the body 1.

8 designates the bearing-rollers, positioned within the carriage 7 so asto rotate freely therein on the bearing-plate 3.

9 designates a bolster-receiving plate that receives the body-bolster ofthe car, which bolster may be suitably secured to said plate, such as bybolts passed through ears 10. (See Fig. III.)` Fixed to the under sideof the plate 9 is a hardened-metal bearing-plate 12, that is adapted toride on the rollers 8, as seen in Figs. II andIII.

13 designates a rock-shaft mounted in sockets 14, contained by the sidewalls of the body 1. Fixed to one end of the rock-shaft 13 is arocker-arm 15, that is provided with an extension-head 16, that projectsupwardly beyond the carriage 7 into a position between two lugs 11,projecting from the outer face of the bolster-receiving plate 9, suchengagement between the rocker-'arms 15 and bolsterreceiving plate 9providing for the movement of said parts in unison with each other. Onthe other end of the rock-shaft 13 is a rockerarm 17. The rocker-arms 15and 17 are preferably both provided with connection to the carriage 7 bymeans of links 1S, one end of one of said links being pivotally joinedto the rocker-arm 15 and the opposite end being pivotally joined to thecarriage and the other link being similarly connected to the rocker arm17 and the carriage.

It will be seen from the foregoing that any movement of the body-bolsteris communicated to the bolster-receiving plate 9, and the movement ofsaid plate in turn acts to move the carriage 7 by reason of theengagement between said plate 9 and the rocker-arm 15 and the connectionby the links 18 from the rocker-arms 15 and 17 to the carriage 7. Thecarriage is therefore always retained centralized beneath the bolsterand the plate 9,that receives said bolster, so that the rollers 8 are incorrect position to receive the Weight from the bolster to which theyare subjected.

While we have described the rock-shaft as being carried by thetruck-bolster and having engagement through an arm with thebody-bolster, yet it is evident that the vparts might be inverted orturned upside down, so that the body-bolster would carry the shaft andthe arm having engagement with the trnck-bolster. i

The leading feature of our invention is that involved in a carriageprovided with rollers and which is interposed between the truck andbody-holsters in combination with a rock-shaft carried by one of theholsters and having an arm which has engagement with the other bolster,said arm being pivotally connected to the carriage, so that as the truckpivots on its center bearing the carriage will be caused to move withoutany frictional binding between the arm of the rock-shaft and thecarriage.

It will be seen by referring to Fig. 1V that the head 16 of therocker-arm 15 extends above the lugs 11, carried by thebolster-receiving plate 9, the said head being thus extended to asufficient height to render it irnpossible for the head to becomedisengaged from the bolster-receiving plate in any vibration or movementof the plate and the bolster thereon.

We claim as our invention- 1. In a side bearing, the combination of abody carried by the truck-bolster, the carriage movably mounted on saidbody, a rockshaft journaled in said body, a rocker-arm carried by saidrock-shaft and engaging a plate carried by the body-bolster, and a linkconnecting said rocker-arm to said carriage, substantially as described.

2. In a side bearing, the combination of a body, a carriage movablymountedon said body, a rock-shaft journaled in said body, rocker-armscarried by said rock-shaft, links connecting said rocker-arms to saidcarriage, one of said links having an extension-head, and abolster-receiving plate surmounting said carriage and provided with lugsbetween which the extension-head of said rocker-arm is arranged tooperate, substantially as described.

3. In a side bearing, the combination of a carriage provided withrollers and interposed between the truck and body-holsters of arailway-car, a rock-shaft carried by one of said bolsters and having anarm that has engagement with the other bolster, and a link pivotallyconnecting said arm to said carriage, substantially as set forth.
